A method of authenticating a user of a computing device is proposed, together with computing device on which the method is implemented. Programmable devices such as FPGAs, CPLDs, etc. A driver of the vehicle is guided to temporarily park at the parking spot to obtain local information including traffic regulations in a country heshe is going to enter. In an embodiment of the invention, the first and second accelerometers are advantageously swapped at a value of the roll angle which is substantially equal to 45\xb0. The Mo:Si ratio is between about 15:1 and about 22:1 for enhanced ductility with a Laves phase.
